Do countries have the data they need to measure progress against the proposed post-2015 development goals and targets? As Kristen Stelljes described in her recent blog post, a Post-2015 Data Test is underway to answer that very question in real time. Through this project, local think tanks and research institutions in countries across the world are investigating what data is available to measure proposed post-2015 targets. Check out the latest updates from Turkey, Bangladesh, Tanzania, and Senegal, and a blog update from Sierra Leone on strengthening data and statistics at the national level.
